Did Mary Isabel Hayhoe pass through Canada?

Did Mary Isabel Hayhoe pass through Canada?

I am trying to find out how my great grandmother got to the US from England. Census records indicate she came either 1885 or 1888. Her mother died in 1885 and her youngest son was born the same year. Census records indicate he was born in Canada/Eng. I wonder if they were traveling and perhaps his mother died in route? Her death is recorded in England. This is a real mystery and I'm afraid the immigration and border crossing records are not available. Mary's parents were George Perfect Hayhoe and Susannah Burdis Hayhoe. Mary had two brothers Joseph and Benjamin. Benjamin was born 1885. Any insight would be appreciated.
